9.8.4 USB Interrupt Register 2
EOPFR — End-of-Packet Flag Reset
Writing a logic 1 to this write-only bit will clear the EOPF bit if it is set.
Writing a logic 0 to the EOPFR has no effect. Reset clears this bit.
RSTFR — Clear Reset Indicator Bit
Writing a logic 1 to this write-only bit will clear the RSTF bit if it is set.
Writing a logic 0 to the RSTFR has no effect. Reset clears this bit.
TXD2FR — Endpoint 2 Transmit Flag Reset
Writing a logic 1 to this write-only bit will clear the TXD2F bit if it is set.
Writing a logic 0 to TXD2FR has no effect. Reset clears this bit.
RXD2FR — Endpoint 2 Receive Flag Reset
Writing a logic 1 to this write-only bit will clear the RXD2F bit if it is set.
Writing a logic 0 to RXD2FR has no effect. Reset clears this bit.
TXD1FR — Endpoint 1 Transmit Flag Reset
Writing a logic 1 to this write-only bit will clear the TXD1F bit if it is set.
Writing a logic 0 to TXD1FR has no effect. Reset clears this bit.
RESUMFR — Resume Flag Reset
Writing a logic 1 to this write-only bit will clear the RESUMF bit if it is
set. Writing to RESUMFR has no effect. Reset clears this bit.
TXD0FR — Endpoint 0 Transmit Flag Reset
Writing a logic 1 to this write-only bit will clear the TXD0F bit if it is set.
Writing a logic 0 to TXD0FR has no effect. Reset clears this bit.
RXD0FR — Endpoint 0 Receive Flag Reset
Writing a logic 1 to this write-only bit will clear the RXD0F bit if it is set.
